gas listing bug

[Geoff Berry]

Hi,

I ran across a bug in listing file generation that was crashing gas.  I
tracked the problem down to a file ending with a long line (~100 characters)
and no newline.  Here's a patch that fixes the problem:

	* listing.c: Don't write past the end of `line' when EOF is reached.
